The Problem

You've written great prompts.
Now you can't find them.

Every AI power user has the same problem. The prompts that save you hours are buried in random places — and you're either re-typing them from memory or starting from scratch every time.

📄

Hunting through a 40-tab Google Doc

You saved that perfect copywriting prompt somewhere in a shared doc. Now it's buried under 200 other lines and Ctrl+F is no help because you can't remember how you titled it.

💸

Paying $9/month just to organise text

Notion, Obsidian, or a dedicated "AI prompt" SaaS — they all want a monthly fee for what is, at its core, storing and searching text. That's not a subscription problem. It's a file problem.

🔁

Re-typing the same prompt from memory

You know the structure of your best SEO brief prompt. But memory degrades. Every time you reconstruct it from scratch, you lose something — and the output is a little worse each time.

All your prompts.
Forever.

FAQ

Quick answers

Do I need to install anything?
No. You download one HTML file and open it in Chrome, Firefox, Safari, or Edge. That's it. No Node.js, no Python, no app store, no installer.
Where is my data stored?
Everything stays in your browser's localStorage — on your machine. Nothing is sent to any server. PromptVault makes zero network requests at runtime.
What if I switch computers?
Use the Export button to download your prompts as a JSON file, copy it to your new machine, open PromptVault there, and Import. Done in under a minute.
Will it work on my iPhone / Android?
Yes — open the file in your mobile browser and it works. The layout is responsive and collapses to a single-column view on small screens.
Can I share my prompt library with a teammate?
